US 12,672,158 B2 · Transponder signaling for localization on higher bands

Abstract

Methods, systems, and devices for wireless communications are described. Some wireless networks may maintain up-to-date location information for the UE by periodically determining the location the UE using a low power transponding mechanism while the UE is in an inactive state. The UE may monitor a first beam to receive one or more transponder search signals during one or more transponder occasions, and between paging attempts from one or more of the base stations of the network. The UE may receive the one or more transponder search signals, and may transmit a transponder response message to a base station including a UE identifier associated with the inactive state. The base station may receive the transponder response message, and may conduct various location measurements for the UE using the transponder response.

Dependent claims

A method for wireless communications at a base station, comprising:

identifying a transition of a user equipment (UE) from a connected state to an inactive state;
transmitting, during a first transponder occasion, a transponder search message that comprises an identifier associated with a notification area of the base station via a first beam;
receiving a first transponder response message comprising a second identifier associated with the UE;
determining a location of the UE based at least in part on the first transponder response message;
identifying a first periodicity for a plurality of transponder occasions associated with the notification area, the plurality of transponder occasions comprising the first transponder occasion;
and
transmitting the transponder search message in each of the plurality of transponder occasions in accordance with the first periodicity.

4 more elements

An apparatus for wireless communications at a base station, comprising:

one or more processors;
and
one or more memories coupled with the one or more processors, the one or more memories comprising instructions executable by the one or more processors to cause the apparatus to:
identify a transition of a user equipment (UE) from a connected state to an inactive state;
transmit, during a first transponder occasion, a transponder search message that comprises an identifier associated with a notification area of the base station via a first beam;
receive a first transponder response message comprising a second identifier associated with the UE;
determine a location of the UE based at least in part on the first transponder response message;
identify a first periodicity for a plurality of transponder occasions associated with the notification area, the plurality of transponder occasions comprising the first transponder occasion;
and
transmit the transponder search message in each of the plurality of transponder occasions in accordance with the first periodicity.
